Not enough DNA test results to issue a prediction at "today"

[giadasp]

Dear Tom Schenk Jr,
I'm sorry if I'm asking something obvious but I'm a freshman in programming and I'm encountering 2 different problems in Running the app.R code (Run with sys.time=2017-11-18 12:43:00"):

1. The datasetUrl value "https://data.cityofchicago.org/Parks-Recreation/Beach-Lab-Data/2ivx-z93u/data" gives the error 403, so I changed this value to "https://data.cityofchicago.org/api/views/2ivx-z93u/rows.csv?accessType=DOWNLOAD" and then I'm able to assign the datatable to labPortal. Have I done the right thing?

2. Then I tried to generate predictions but the variable readyToModel is FALSE and so I'm not able to perform the predictions. So I tried to change the today value to an old date (such as may 2017) but readyToModel is still FALSE.

What I can do to solve these issues?
Thank you

Giada

Hi @giadasp, I've taken a look at this issue and I wonder if you've tried the datasetURL from the code, which is "https://data.cityofchicago.org/Parks-Recreation/Beach-Lab-Data/2ivx-z93u". The URL in your comment above has /data appended to it.

There is an open issue in RSocrata about the /data issue. As it stands currently, read.socrata() supports the URL that takes you to the "landing page" of the actual dataset, but does not support the "grid view" (e.g., /data) URL.

Once you get past the 403 error, make sure you use a value for today which has the prerequisite DNA test results here, such as 9/4/2017.

1.If I remember well I tried also without '/data' but it didn'twork as well

2. I tried with 9/4/2017 and I had some predictions but I couldn't be able to upload them compiling all the code.

Ok I see. If you could post the code where you're getting the error, I can take a look.
